Description
The Triconex 3625 is a 32-point TMR Supervised/Non-Supervised Digital Output Module for the most critical control programs in Triconex Safety Instrumented Systems (SIS). The 3625 receives output signals from the Main Processors on each of three channels, and each set of three signals is voted by special quadruplicated output circuitry on the module. The circuitry of the 3625 produces one voted output signal and passes it to the field termination, with the quadruplicated voter circuitry providing multiple redundancy for all critical signal paths to guarantee safety and maximum availability.
The 3625 provides 32 digital output channels in a commoned configuration, with a nominal voltage of 24 VDC and an operating voltage range of 16–32 VDC (maximum 36 VDC). The 3625 delivers a maximum continuous current of 1.7A per point, with a surge current capability of 7A per 10ms. The typical voltage drop of the 3625 is less than 2.8 VDC at 1.7A. The minimum required load current for the 3625 is 10 mA, with a maximum load leakage current of 4 mA.

Each SDO module has voltage andcurrent loopback circuitry coupled withsophisticated online diagnostics thatverify the operation of each outputswitch, the field circuit and the presence of a load. This design providescomplete fault coverage without theneed to influence the output signal.
The 3625 TRICONEX Digital Output Module may still be available for purchase and support from Amikon Limited beyond End-Of-Life (EOL) by the manufacturer (OEM).

The 3625 implements Triple Modular Redundancy (TMR) at the module level. Each of the three independent channels receives digital output commands from the three Tricon Main Processors over the triplicated I/O bus. The channel outputs are then voted by quadruplicated power transistor circuitry to produce a single, highly reliable output signal to the field device. This architecture ensures that a fault in any single channel—whether due to processor failure, wiring error, or power transistor degradation—cannot cause either a dangerous failure-to-energize or a spurious trip that would disrupt process operation. The quadruplicated voter provides multiple redundancy for all critical signal paths, achieving IEC 61508 SIL 3 capability for safety instrumented functions.

Connect the dedicated Tricon system interface cable from the backplane slot to a compatible 16-point commoned External Termination Panel (ETP) using standard ELCO connectors.Land all field circuit wiring onto the ETP terminal strips.Keep returns and commons segregated strictly as indicated by your system loop drawings.
Technical notes
Diagnostic capabilities are comprehensive on the 3625, including per-point ON/OFF state indicators, module status indicators (PASS, FAULT, LOAD, ACTIVE), and field alarm indicators (LOAD, 1 per point). These diagnostic features of the 3625 enable rapid fault identification and facilitate preventive maintenance. The 3625 is called "supervised" because fault coverage is extended to include potential field problems; the field circuit is supervised by the module so that field faults such as open or missing load, field shorts resulting in load energization in error, and shorted loads in the de-energized state can be detected.
FAQs
-
What is the 3625 ？
+The Triconex 3625 is a highly reliable 32-point, 24VDC Digital Output module engineered by Schneider Electric (Invensys). Utilizing Triple Modular Redundancy (TMR) technology -
What are its maximum voltage and current tolerances?
+It operates at a nominal 24 VDC but supports a maximum voltage of 36 VDC. It handles a maximum continuous current of 1.7A per point and a temporary surge up to 7A for 10ms. -
What level of electrical isolation does it have?
+The circuitry offers 1,500 VDC of point-to-point isolation. -
What is the difference between the 3625 and the 3625A module?
+The modified 3625A splits the field power distribution into isolated groups of 16 points rather than one continuous bus. The 3625A is fully backward-compatible but requires explicit wiring adjustments across field termination panels.
